“…These systems are characterized by the definition and classification of the four most important variables in the pathology: defects, causes, diagnosis techniques and repair techniques, as they also established quantitative correlations . Following a systemic approach, studies were published about the following nonstructural elements in buildings: i) Waterproofing of roofs (Walter et al, 2005); ii) Ceramic coverings for floors and walls (Silvestre and de Brito, 2009; Silvestre and de Brito, 2010; Silvestre and de Brito, 2011); iii) Epoxy coatings for industrial floors (Garcia and de Brito, 2008); iv) Slab walls (Gonçalves et al, 2013(Gonçalves et al, , 2014; v) Coatings for wood floors (Delgado et al, 2013); vi) Natural stone claddings for floors and walls (Neto and de Brito, 2011;Neto and de Brito, 2012) vii) Divisions made of laminated plaster (Gaião et al, 2011;Gaião et al, 2012); viii) Common friezes on internal facades (Palha et al, 2012;Pereira et al, 2011); ix) Coatings on inclined roofs (Garcez et al, 2012;Garcez et al, 2015a;Garcez et al, 2015b); x) Plaster on walls (Sá et al, 2015a;Sá et al, 2015b);…”

La comunidad científica internacional ha dedicado mucha atención a la vasta área de conocimiento de la inspección, diagnóstico, mantenimiento y rehabilitación de edificios, que se puede utilizar en el desarrollo de sistemas de gestión de edificios integrados. En este artículo, se realiza un encuadramiento de los métodos de evaluación de patología en elementos no estructurales de los edificios, basado en los actuales, presentando algunos de los desafíos en esta área. También se presenta un modelo a implementar en sistemas integrados de gestión de un edificio, formando una línea conductora y una base consistente para un sistema que se ponga en su lugar.

“…The lack of maintenance and rehabilitation policies implemented during the lifetime of the buildings is especially noticeable in the envelope elements (façades, windows and roofs), promoting the premature aging of these elements. The building's envelope elements are the first protection of the buildings [14] against the external environment degradation factors [15], and the roofing systems are the most vulnerable element [16]. According to several authors [17][18][19][20], roofing systems are the building element most affected by anomalies.…”

Existing maintenance policies have several limitations, mainly due to the lack of knowledge regarding the durability and performance of buildings. Usually, the maintenance policies are insufficiently accurate, neglecting the risk of failure over time and the global costs associated with repairs. In this study, a condition-based maintenance model, based on Petri nets, is proposed to evaluate the impact of three maintenance strategies of ceramic claddings in pitched roofs (CCPR): MS1—only total replacement; MS2—composed of total replacement and minor intervention and MS3—composed of total replacement, minor intervention and cleaning operations. In this study, 146 CCPR were inspected in situ, with a total area of 43,991.6 m2. The remaining service life of the CCPR; the global costs over the claddings’ lifetime (considering inspection, maintenance, replacement and disposal costs); the claddings’ degradation condition and the number of replacements during the time horizon are used to evaluate the performance of the different maintenance strategies through a simplified multi-criteria analysis. The results show that the gains in performance, in terms of expected service life and durability, of the consideration of preventive maintenance actions (minor interventions or cleaning operations) outweigh the increase of the operation costs.

“…Prescribing the most appropriate diagnostic methods and repair solutions to eliminate the defects and corresponding causes is another useful asset of the system (2). The work of Delgado et al (1) proposes such an inspection system for WF, based on a methodology also tested on gypsum plasterboard walls (3), gypsum plasters (4), renderings (5), ceramic tiling (6), natural stone cladding (7), external thermal insulation composite systems (8), flat roof waterproofing systems (9), pitched roof claddings (10), industrial floor coatings (11), architectural concrete surfaces (12), and door and window frames (13). This methodology was adapted to the specific WF technology and the study of floorings' pathological processes.…”

Defect characterization, diagnosis and repair of wood flooring based on a field survey

et al. 2018

View full text Add to dashboard Cite

A statistical characterization of defects in 35 buildings and 98 wood floorings (softwood and hardwood floors, and laminated and engineered wood floors), their diagnostic methods and repair solutions is presented. An expert system for inspecting wood flooring, comprising the classification of defects, their most probable causes, diagnostic methods and repair techniques, was used. Results include age, affected area, severity and frequency of defects and their main causes, as well as appropriate diagnostic methods, preventive and curative repair solutions most prescribed and the most significant correlations. Scratches were detected in more than five sixths of the sample, highly associated with exterior mechanical actions, and with an inadequate finishing layer. Wearing of the finishing layer was detected in a quarter of the inspected floorings. Accordingly, the application of a suitable finishing layer and, alternatively, its replacement are the most prescribed repair techniques.
